WebApr 4, 2024 · Clearly, the Bregman distance $D_h$ is defined as the residual of the first order Taylor expansion of function h. In general, the Bregman distance is asymmetric with respect to the two arguments. On the other hand, the convexity of function h implies the non-negativity of the Bregman distance, making it behave like a metric. fire truck front view
